I’ve got following issue:
Trunk between servers configured, if Allow Anonymous Inbound SIP = yes - calls pass.
But the task is to move Allow Anonymous Inbound SIP to No and save the ability to call.
Is it possible? I would like to put external network Or address of another server somewhere in the configuration and establish a connection. But I do not know what to write and where. Google has not helped for now.
Any help is appreciated.
